NB3W1900L

NB3W1900L 3.3 V 100/133 MHz Differential 1:19 HCSL-Compatible Push‐Pull Clock ZDB/Fanout Buffer for PCIe[ www.onsemi.com Description The NB3W1900L differential clock buffers are designed to work in conjunction with a PCIe compliant source clock synthesizer to provide point-to-point clocks to multiple agents. The device is capable of distributing the reference clocks for Intel® QuickPath Interconnect (Intel QPI), PCIe Gen1/Gen2/Gen3.The NB3W1900L internal PLL is optimized to support 100 MHz and 133 MHz frequency operation. The NB3W1900L is developed with the low-power NMOS Push-Pull buffer type. Features 19 Low Power Differential Clock Output Pairs @ 0.7 V Output-to-Output Skew Performance: < 85 ps Cycle-to-Cycle Jitter (PLL Mode): < 50ps Low Phase Jitter (Intel QPI, PCIe Gen 2/Gen 3 Phase Jitter Compliant) Input-to-Output Delay Variation: < 50 ps Fixed-Feedback for Lowest Input-to-Output Delay Variation Spread Spectrum Compatible; Tracks Input Clock ...
